To all 'whom t may concern:

Be it known that I, J AcoB BEI-3mi., of Mifflintown, in the county of Juniata and State of Pennsylvania, have invented a new and ImprovedWinnowing-Machine for Separating Impurities and All Foreign Substancesfrom Grain; and I do hereby declare the following to be a full, clear,and exact description of the construction and operation thereof,reference being had to the accompanying drawings, making a part of thisspecification, in which- Figure l, is a top view; Fig. 2, is a sideelevation; Fig. 3, a vertical longitudinal section, and Figs. 4, and 5,are portions of the same detached.

L, is the concave inclosing the fan;p, p, are the Wings of the fan; 11is a pinion on the fan shaft; m, is the driving cog wheel working intothe pinion n; 7c, is a crank on the axle of the driving cog wheel.v

A, is the shoe in which is placed the screen J. The shoe is the entirewidth of the machine; its sides pass into and work in openings in theside casings of the machine; by which arrangement screens V.of muchlarger size than usual can be made use of, and the entire blast of thefan'can be concentrated upon the screens-there being no openings at thesides of the shoe, for the The shoe is suspended by the hooks e, at itsfront end, and is supported by the vertical springs h, at its rear end;it receives a horizontal longitudinal reciprocating mot-ion from thepitman F, operated by a crank on the fan shaft.

E, is an inclined board, the ends of which are let into and secured tothe sides of the shoe A. The inclined board E, forms the bottom of thehopper, and has recesses cut in, its upper surface forming l abruptshoulders o, o, rising one above the other in regular succession. Theobject of the shoulders in the inclined board E, is to regulate the feedof the grain from the hopper to the screen J, and t0 prevent the strawand chaff mixed with it, from clogging and choking the passage from thehopper, the first time the grain is passed through the machine; whichthey eect in consequence of the forward and back reciprocating movementof the shoe, thus enabling the shoulders on the inclined board E, totake hold of the chaff and grain, and force the same out of the aperturein the hopper on to the screen J.

After the grain has been passed once through the machine, and separatedfrom straw and chaff; the false bottom D, is placed in the hopper, andthe feed is regulated byv the adjustable gate S. The grain chaff, andstraw, falls from the inclined board E, on to a series of vibrating arms(Z, d, forming a separator for removing the straw and chaff from thelgrain, previous 4to its falling upon the screen. The curvedV wire armsd, cl, are inserted into the shaft c,

yhaving its bearings in the sides of thelshoe A. The shaft c,reciprocates with the shoe A, and is vibrated on its axis by means of acrank f, on the end of the same, and the vertical pitman g, jointed tothe horizontal pitman F; yconsequently the separator has at the sametime a compound reciprocating, and a vibratory motion, by which it isenabled to throw the straw upward and rearward out of the machine. ,Thegrain falls'VV from the screen J, on to the apron B,which conducts it tothe front of the machine.

J ,-is a screen let into and forming a part of the apron B; CQC, are aseries ofthin slats placed over the screen, J and secured by joint pinsat each end ofthe same; the outer edges of the slats are connected toeach other vby a` cordV a, by which they can be elevated` and retainedon their edges; or can be Ydepressed and retained in a positionparfallel Vwith the-screen J. When the slats are y depressed, theycompletely cover the screen, and allow the grain to-pass freely over theslats ;'when they are elevated, kthey allow the grain to Vfreely fallupon and pass over the screen J. When the grain is not sufcientlycleaned by the' vibrating screen or screens, the slats C, kC,areelevated frfor it to receive the benefit .ofthescreen J.

H, `is the screen or tail box under the screen J K, `is agageboardinftherear rend of the. machine, for catching the tailings andhead-v ings. y
